The evolution of government housing policy: The case of new south Wales 1901–41

This paper sets out the development of four main threads of housing policy in New South Wales from the latter part of the 19th century through the first 40 years of the 20th century. Following a discussion of the social and political circumstances and debate surrounding government policy regarding landlord/tenant relations, housing quality and supply, and owner occupancy, it concludes that policy evolution is irregular and a product of the exigencies of the political process. It also suggests that although government policy did little to improve the housing situation for the underprivileged, there was nevertheless a growing acceptance by both Labor and conservative parties of the increased need for government intervention in the housing market.     

The superflow state of 3He-B at a diffusive wall. Quasiclassical calculations

We report on first computations considering effects of a rough wall on the counterflow state in superfluid ³He-B for high flow velocities. Using the quasiclassical Green's-function formalism supplemented by the boundary conditions for a diffusive wall, we calculate the order-parameter field and the supercurrent near a container wall for various pressures and temperatures. One of our results is that the current density at the wall as a function of the flow has a maximum at the velocity which is about half of the pair breaking velocity.     

The effect of coil parameters on the distribution of steep-frontedsurges in machine windings

The authors identify the coil parameters that are of importance, when assessing interturn voltages produced by steep-fronted transients. The studies are based on a multiconductor transmission line computer model of a machine winding energized by a simple ramp function. Variations in interturn voltages produced by changes in insulation thickness, insulation permittivity, turn geometry, coil length and number of turns are examined and certain guidelines for avoiding high interturn voltages are evaluated. An application study is included to show how interturn voltages can be significantly reduced by applying these guidelines     

A new bubble-point-pressure correlation for the binary LiBr/H2O solution

In accord with the increasing concern about the global environmental issues, the absorption refrigeration heat-pump systems are currently being considered very promising and attractive. For the purpose of supporting the advanced R&D technology in this area, we have developed a novel correlation to represent the bubble-point pressures of LiBr H₂O solutions. The developed correlation covers the most extensive range of validity ever proposed: 273–483 K for temperatures, 0.05 kPa to 1.0 MPa for pressures. and 29 76 wt% LiBr for concentrations.Paper presented at the Twelfth Symposium on Thermophysical Properties, June 19–24, 1994.

Significance of DNA ploidy in the treatment of T1 glottic carcinoma

OBJECTIVE: To assess the role of DNA ploidy as a predictor of radioresistance in T1 glottic carcinoma. DESIGN: Case-control study. Flow cytometric DNA ploidy measurements were performed on formalin-fixed paraffin-embedded tumor specimens from 15 patients with T1 glottic laryngeal carcinomas in whom radiotherapy had failed and from a matched group of 15 patients in whom an identical radiotherapy regimen was curative. Analysis of DNA content was performed blind to outcome of treatment. SETTING: Academic tertiary referral medical center. PARTICIPANTS: Thirty patients with clinically staged T1, N0, M0 glottic carcinoma. INTERVENTION: All patients received radiation to the larynx through opposed lateral ports at a total dose of 64 to 70 Gy. RESULTS: Ten diploid and five aneuploid histograms were found in the resistant group, and six diploid and nine aneuploid histograms were found in the radiosensitive group. This difference was not statistically significant. A trend toward a higher relapse rate after radiotherapy (62.5%) among patients with diploid tumor compared with those with aneuploid tumor (35.7%) was noted. CONCLUSIONS: DNA ploidy did not predict response to radiotherapy in patients with T1 glottic cancer, probably because of the small number of patients. A trend toward lower risk of local recurrence after radiotherapy in aneuploid tumors was noted. A larger prospective study is needed to assess the value of DNA ploidy in the treatment of early laryngeal cancer.     

DETERMINATION of the MIXING INDEX of PADDY GRAINS UNDER VIBRATING CONDITIONS

Mixing of ingredients is an important operation in processing of food for obtaining the better quality product. A laboratory set‐up capable of modulating both frequency and amplitude of vibration of the grain bed was used to determine the mixing indices of paddy grains under varied experimental conditions. the mixing indices of three different types of paddy grain for three different grain bed depths were determined. the parameters varied were the vibration amplitude, frequency and the mixing time, respectively from 2 to 10 mm, 10 to 50 Hz and 5 to 120 s. Three varieties of paddy (short bold, medium slender and long slender) were used in the experiments with different length‐breadth ratio (slenderness ratio, μ, of 5.77, 4.48 and 2.70). Response surface methodology was adopted to optimize the amplitude and frequency of vibration of the mixing device. the results revealed that, the optimum frequency and amplitude of vibration for the medium slender (μ= 4.48) variety of paddy were 20–22 Hz and 8–9 mm, respectively for all the three grain bed depths of 25, 12 and 6 mm. Irrespective of grain bed depth, all the three different types of paddy showed maximum mixing indices value after 1 min of mixing. Extending the mixing time did not have any effect on mixing indices. the effect of bed depth was found to be insignificant for short bold variety of paddy.     

Equitone Predicate Algebras and Their Applications

Predicates that preserve their values on a larger (extended) body of data are called equitone. An algebra of such predicates is constructed, a system of its generators is specified, and a complete system of transformations of identities is defined. The results obtained are used for construction and investigation of complete classes of compositions of various types and levels of abstractions that are used in logics of partial predicates.
